Analog VDO speedometer failure.

<< < (2/2)

Mike And Mary Engen:
Follow up as promised earlier:

Cruise was working when speedometer wasn't, so decided rather than crawling under coach, just to replace the speedometer.
Found a replacement 3-3/8" VDO Vision 0-85 MPH/Kilometer electronic from Summit Racing via Ebay for a "Buy It Now"
price of $119 vs. $399 from others (Spartan, etc.)  This is a conversion from electrical/analog odometer to an electronic
odometer (analog needle).

Installed new speedometer today, now have lights, diagnostics tested ok, and only have to calibrate at a measured mile nearby
and it will be functioning fully.

For others with the Spartan Chassis:
Wire 31 +instrument lamps splices to the top two lamp quick disconnect prongs.
Wire 14 -instrument lamps ground splices to bottom two lamp quick disconnect prongs.
Wire 40 instrument 12v power goes to pin #4.
Wire 417 + comes from Cruise to speedometer and goes to pin #8
Wire 23 - speedometer negative goes to pin #7.

Wires 417 & 23 were previously paired on the old speedometer. Without a schematic, I believe these are both pulse generator
wires that work in conjunction with the cruise. I will try to research a little more or maybe somebody else knows.

This is a very easy to do project on older Beavers that have the round speedometer and access by removing velcroed dash
panel.

The manufacturers install sheet explains the simple calibration.
